To (all whom it may concern; 7

Be it known that I, EDWARD F. ABBEY, of Toledo, in thecounty of Lucas,State of Ohio, have invented certain new and useful Improvements inBrush-Machines; and I do hereby declare the following to be a full,clear, and exact description of the same, reference being had to theaccompanying drawings, forming a part of this specification, and to theletters of reference marked thereon.

The present invention relates to improvements in machinery used in themanufacture of brushes, and more especially to improvements in thatclass of machinery designed for the manufacture of brushes having whatare known as solid backsthat is to say, brushes having backs in whichsockets are drilled or similarly formed at proper distances apart and atproper relative angles for the reception of the bristles or tufts ofbristles and the bristles are subsequently inserted in said sockets andheld therein by suitable anchors-althongh the improvements contemplatedin the present application are capable of a wide range of usefulness andmay be employed to advantage in connection with any desired type ofmachine whereinit may be found advantageous to position a blockautomatically and in accordance with a previously-designed system eitherfor the insertion of the bristles or for the formation of the sock etsfor the reception of the bristles.

In illustrating the present improvements they have been shown' inconnection with a machine for inserting bristles commonly known as afilling-machine, the mechanism illustrated for performing the actualfilling operation aside from the positioning of the block being awell-understood type of machine now in common use and known as the Ganefilling-machine, said machine being well illustrated in United StatesPatent to J..

V. Gane, No. 378,130,dated February2l, 1888.

The present invention consists in certain novel details of constructionand combinations and arrangements of parts, all as will be hereinafterdescribed, and pointed out particularly in the appended claims.

In the accompanying drawings, Figure l is a perspective view of amachine embodying the present improvements, the pattern-cams beingremoved, but indicated in dotted lines,

and certain portions being broken away in order to show more clearlyparts which would otherwise be concealed thereby and the fillingmechanism proper being indicated in outline only in order that itsrelation to the mechanism constituting the present invention may beclearly understood. Fig. 2 is a plan view of the adjustablecontrolling-guide for the brush-blockcarrier. Fig. 3 is an elevation ofa block carrier, showing the adjusting mechanism for the clamps. Fig. 4is a detail View of the stop mechanism controlled by the pattern-camshaft for arresting the movement of the'machine when the pattern-camshave reached a predetermined point in their movement. Fig. 5 is afurther detail of parts of the stop mechanism which cooperate with thedrive-shaft, said parts being shown separated. Fig. 6 is an elevation ofone of the patterncams. Fig. 7 isa plan of a brush-back, showing thecourse traversed with relation to the tool or inserter. Fig. 8 isadetail section of the holder for the clamp-screw. Fig. 9 is a.

detail of the operating mechanism for the centering and advancing pointand also showing a portion of the block-carrier and templet. Fig. 10 isa detail perspective showing the stopping mechanism and parts associatedtherewith.

Like letters of reference in the several figures indicate the sameparts.

The machine for inserting the bristles or tufts, as illustrated in theaccompanying drawings, is indicated generally by the letter A, itsdrive-shaft by the letter B, and the inserter by the letter C, and itwill be understood that the bristles are in the well-known mannerseparated, advanced to the inserter, and by the latter inserted in thesockets provided for the tufts when a brush-back containing sockets ispresented in properposition for the cooperation of the inserter. Thedrive-shaft for the filling-machine also constitutes the drive-shaft'forthe mechanism for automatically positioning the block and for advancingthe block toward and from the inserter, the mechanism for effecting thelatter movement being substantially similar to that heretofore employedin filling-machines, as will be hereinafter pointed out.

The brush-block positioning and presenting mechanism referredv to islocated in rear of the filling-machine and embodies a baseframe D and atop frame D, the latter being in the form of a table-top upon whichcertain of the parts are mounted.

The block-carrier is in the form of a pair of clamps E, mounted to slideon guide-rods E and adapted to be adjusted toward and from each other bya central adjusting-screw E having right and left threads thereon, saidscrew and clamps being bodily adjustable in order to position the clampssimultaneously with relation to the filling-machine or other workingparts of the machine. The guiderods E are mounted in or constitute aportion of a frame having heads E and rearwardly-extending rods Eadjustably mounted in trunnion-blocks E the latter being pivoted in linewith each other in a swinging naled in line with each other on theforward end of a longitudinally-movable frame G. This frame G isprovided with rearwardlyextending shafts G, adapted to slidelongitudinally in bearings G on the table D and to be moved toward andfrom the inserter in line therewith. Thus while the block-carrier may beadjusted on two centers at right angles to each other, so as to vary itsangle with relation to the inserter in its movements toward and from theinserter, it moves in a definite line, thereby insuring the insertion ofthe bristles uniformly with relation to the sockets for holding thesame.

The mechanism for moving the block-carrier toward and from the inserterpreferably consists first of a centering and advancing point H, adaptedto cooperate with a templet I, secured in rear of the clamps E andhaving apertures formed therein corresponding, but reversely arranged,with respect to the sockets in the brush-back. This centering andadvancing point is adjustably mounted on the forward end of a slide H,which slide H corresponds to the slide heretofore employed in the Ganefillingmachine for directly advancing the brush-block. The operating andcontrolling mechanism for the slide is similar to the mechanismheretofore employed in the Gane machine for alike purpose and consistsof a rock-shaft H having an upwardly-extending arm H the upper end h ofwhich cooperates with the under side of the slide through the usualwellknown connections, and a downwardly-extending arm H is connected atits lower end by a connecting-rod H with a lever H pivoted to the frameof the filling-machine, adapted to be moved by a cam it on thedrive-shaft of the filling-machine. On the return movementit isnecessary that some play or independence of movement should be allowedthe advancing and centering point in order that it may be eifectuallydisengaged from the templet prior to the time when said templet andblock are adjusted laterally for the insertion of a tuft in a new ordifferent socket, and for this reason the initial retrograde movementpreferably first moves the advancing and centering point to withdraw itfrom the templet, the movement of the block-carrier taking place afterthe said point has retreated sufficiently far to be disengaged from thetemplet. To prevent immediate movement of the carrier, a friction deviceis preferably provided which will hold the carrier until the point hasmoved a certain distance, and the friction is preferably provided byarranging the bearings G to clamp the rods with a greater or lesspressure, as desired. The return or retrograde movement of the carriermay be effected or inaugurated by lateral projections h on the point,adapted to cooperate with vertically-extending rods 72, on the carrier;but in addition to this means for effecting such movement a spring K isalso pro vided, located between a cross-head K, connecting the rods G,and a fixed abutment K on the frame D. In adjusting this portion of themechanism it will be understood that the friction of the hearings inwhich the rods G work should be sufficient to prevent the spring frommoving said rods and the blockcarrier until the advancing and centeringpoint has moved a short distance toward the rear.

Mechanism for adjusting the angular position of the block-carrierpreferably cooperates directly with said carrier or with thecarrierframe, and in the present instance it consists of a verticallyand horizontally adjustable track or guideway L, upon which is guided ashoe or block M, pivotally mounted on the lower portion of theblock-carrier, the pivotal connection being such as to permit theblock-carrier and its frame to swing transversely, while the shoe Mmoves on the track as the latter rises and falls, and permit saidcarrier and its frame to swing vertically on the centers formed by thetrunnion-blocks F. The track or guide L is preferably mounted uponorconstitutes a portion of a framing, the remaining portion of which isformed by parallel rods L, Fig. 2, connected at the ends and mounted toslide longitudinally in bearings on a vertically-adjustable support N.Thus the angular position of the block-carrier may be adjustedvertically by the vertij cal movement of the support N and transverselyby the movement of the track-frame L on said support N, and suitablemechanism is provided for effecting the movements of the support andtrack automatically under the control of pattern-cams, which have beenpreviously designed to conform to the particular style of brush beingmade.

The support N is mounted on the upper end of a tubular shaft N, mountedto slide in a fixed bearing 0, and is held against rotary motion by aguide rod N working through an arm 0 on the bearing 0 and connected atits lower end with the shaft .N by an arm N. Thus said shaft and itsguide N and arm N constitute a vertically-movable frame, and this frameis adapted to be moved vertically by a bell-crank lever P, one arm ofwhich is connected through links p with the lower end of the shaft N andthe other .arm of which is connected by a link P withone arm 1? of abell crank lever loosely mounted on shaft L, the other arm P of whichcarries a roller p adapted to cooperate with the periphery of one of thepattern-cams shown in dotted lines in Fig. 1. Obviously by the rotationof said pattern-cam the support N will, through the said connections P,P, P and P be moved vertically, and by properly forming the periphery ofsaid cam the support and track may be moved to any desired degree and soas to change the angle of the block-carrier in a vertical plane withrelation to the inserter to conform to the desired angleand position thebristles shall occupy in the completed brush.

To efiect the transverse movement of the guide or track L, thetrack-frame L is connected by a link L with the end of a crankarm L onthe upper end of a shaft L ex tending down through the tubular shaft Nand provided with a laterally-extending arm L The outer end of arm L isbifurcated and adapted to embrace a vertically-arranged controller Lsaid controller being in the form of an elongated crank having an axiscoincident with the longitudinal center of the shaft N and of the shaftL Thus the shafts N and L may be moved verticallyin unison with eachother, and at the same time the shaft L may be rotated by the movementof its controller L to shift the track or guide L transversely of thesupport N, and thereby swing the block-carrier in a lateral direction,with the trunnion-blocks E as a center.

The vertically-extending controller L is preferably in the form of a rodcarried at its opposite ends on crank-arms L journaled one on thebearing 0 and the other on a bearing 0 on the bottom frame D of themachine, the shaft L extending down through the latter bearing.

The movement of the controller L is effected through a link L jointed atone end to the upper arm L of said controller and at the opposite end toa relatively long crank-arm L on a rock-shaft L, which shaft L alsocarries a second crank-arm L having at its outer end a roller Ll adaptedto cooperate with the other one, of the two pattern-cams indicated indotted lines in Fig. 1, and consequently by the movement of said lattercam the transverse adjustment or positioning of the block-carrier iseffected by the combined transverse and vertical adjustments of saidcarrier, enabling the brush-block to be properly positioned forinserting the bristles in all of the sockets.

The pattern-cams are rigidly mounted on the shaft Q by being clampedagainst the disk Q, and the shaft Q extends through to the oppositesideof the machine, whereit is proranged worm Q carries a ratchet-wheelQ and cooperating with said ratchet-wheel is a pawlq, mounted on anoscillatory carrier q. The pawl itself ispreferably held in engagementwith the ratchet-wheel by spring-pressure, and any ordinary means may beprovided whereby said pawl may be held out of engagement when desiredfor the purpose of rotating or adjusting the pattern-cams by hand, thearrangement shown being similar to that described in my prior patent,No. 666,217, dated January 15, 1901.- The pawlcarrier q is connected bya link g with an eccentric g on the drive-shaft B of thefilling-machine. Thus by the rotation of said drive-shaft thepawl-carrier and pawl are oscillated, and on the movement of said partsin one direction movement is imparted to the ratchet-wheel, worm,worm-gear, and pattern-cam shaft Q, and this movement is timed to occurwhen the block-carrier is withdrawn from the inserter and the advancingand centering point is Withdrawn from the templet on theback or blockcarrier.

The pattern-cams as ordinarily constructed I are preferably of largesize or of suflicient size to permit of the making of a brush by onerotation of said cams, (see Fig. 6,) and when said rotation is completedit is desirable that the mechanism should be automatically brought torest to enable the operator or attendant to remove the completedbrushback and to insert a new back for the subsequent operation.- Forthis purpose thepattern-cam shaft is provided with a stop projection,which at the proper time cooperates with a clutch mechanism to releasethe driving-pulley from the driving-shaft, permitting said pulley tocontinue its movement,while the adapted to cooperate with a springpin T,mounted in a disk T (shown in Fig. 5) and.

keyed to the drive-shaft of the filling-machine. Thepin T when projectedcooperates with a semicircular recess T in a sleeve journaled on saiddrive-shaft and, rigidly connected wit h the driving-pulleys T Theprojection T on the clutch-rod when pressed, toward the driving-shaftwill be in position to ride under the end of the pin T, moving the sameout of the recess 'l and disengaging the drive-shaft from itsdrive-pulleys,v

IIO

vated on the projection T, and in order to again couple the parts it isonly necessary to withdraw the projection T by a longitudinal movementof the clutch-rod in the reverse direction. To enable this movement totake place with the projection R still in position, the end S of saidclutch-rod is pivoted or hinged to the rod and provided with aprojecting operating-arm S with which a slotted link S cooperates. Thelink S is extended out into convenient position to be moved by theattendant, and hence by a pull u pon said link the pivoted end S of theclutchrod may be swung to one side, and the rod under the influence ofits spring S will immediately advance to release the clutchpin T,thereby inaugurating the movement of the machine.

To hold the clutch-rod S in position to retain the clutch disengaged, itis provided with a projection s, with which a latch s is adapted tocooperate whenever the clutch-rod is moved outwardly, andsaid latch s ispreferably in the form of a bell-crank lever, one arm of which isjointed to the link S and is adapted to be operated thereby to releasethe latch at the same time that the jointed end S of the clutch-rod isflexed. The joint between the end S and body of the rod S is preferablya hinge or rule joint, whereby said end is prevented from moving out ofalinement with the rod in but one direction, and the joint is so setthat the pressure of the projection R when it contacts with the end S isin a direction opposite to the direction in which said end can swing,whereby the certain operation of the projection and clutch-rodisinsured. To take up any lost motion which might occur in the joints ofthe mechanism for moving the block-carrier, springssuch, for instance,as those indicated at U and U- are employed for holding the carrier orparts directly connected therewith normally under tension in onedirection, and thus while a variation may occur it will bea uniformvariation and may be compensated for in the contour-lines of thepattern-cams or in the adjustment of the various operating connections.Said springs also preferably serve as the means for moving the block inone direction and hold the rollers down to the cams, while thepattern-cams move it in the opposite direction against the tension ofthe springs. In the vertical movements gravity may perform the samefunction, but is usually assisted by the spring-pressure.

In the normal operation of the machine, as illustrated in the drawings,wherein it is assumed that the sockets have been previously formed inthe brush-backs, a back is placed in position between the clamps and thescrew E tightened to hold the same rigidly in place. Should it be foundthat the brush-back is too high or too low, both clamps, together withthe brush-back, may be bodily adjusted in the carrier-frame by looseningup the internallythreaded jam-nuts W W, which support the screw at theupper end and take a bearing in the frame-head E, Fig. 8, then adjustingsaid nuts and the screw to the new position, when by tightening saidnuts against each other it will be found that the screw has been shiftedbodily, but at the same time it is free to be rotated to advance orretract the clamps when clamping or releasing the brush-back. Thebrush-back having been secured in position and the parts of thefilling-machine adjusted for operation, the mechanism is started by theattendant through the manipulation of the rod S which releases theclutch-rod S. The subsequent operation of the machine is entirelyautomatic, one pattern-cam operating to position the brush-blockvertically, and the other pattern-cam to position the same horizontally,the combined movements permitting of the movement of the brush-block toany desired angle with respect to the inserter. It will be observed thatin the present improvements while the pattern-cams do position thebrushblock the final centering is efiected by means of the centering andadvancing point H, which cooperates with the templet I, preferablysecured immediately in rear of the brush-back and in such position thatthe pressure between said point and inserter is in a direct line. Theadvancing and positioning point is preferably conical, and in thiscooperation with the recesses in the templet it insures a perfectcentering, but at the same time the automatic positioning of thebrush-back is not interfered with, inasmuch as the movements of theparts are so timed that the brush-back is not shifted until after it iswithdrawn from the inserter and until after the centering and advancingpoint has withdrawn from the templet.

In positioning-machines as heretofore constructed to positionbrush-backs it has been customary to provide pattern-cams in which thecontour-lines corresponded to the course traversed by the tool withrelation to the brush-back, said course starting from some definitepoint at one end or side of the brushback and terminating at adiametrically opposite point at the opposite end or side of thebrush-back. The starting-point and the terminating-points of the coursetraversed by the tool with relation to the back necessarily left orformed a wide space between the two corresponding points on the patterncam. This space has usually, taken the form of a high step, over whichthe controlling-arm must be elevated or over which it must pass from thestopping to the starting point, such movement being a dead movement. Inother words, from the stopping to the starting point it required anextreme swing of the carrier, and, furthermore, it has usuallynecessitated the employment of a special means for mov 'ing the parts toenable the controlling-arm which cooperates with the pattern-cam totraverse this space without causing the portions of the mechanism otherthan the positioning devices to be operated. In accordance with thepresent invention the patterncams are so formed that the starting andstopping points are in proximitythat is to say, they are so formed thatthe course traversed by the tool terminates in a socket next adjacentthe socket constituting the startingpoint. By reference to Fig. 7 itwill be seen from the dotted lines extending from hole to hole that thetool travels a continuous course, there being no point of interruption,and by reference to Fig. 6 it will be seen that the pattern-cam isformed with regularcrests and depressions for guiding the tool in itscontinuous course, with no dead or ineffective part. With such anarrangement no extreme or dead movement of the controlling-arm whichcooperates with the pattern-cam is necessary. The starting-point may beanywhere in the course of the travel of the tool with relation to theback, and when all of the sockets have been filled and the machine hascome to rest and upon the insertion of a new back the machine is readywithout the necessity of a dead movement of any of the parts in order-tobring them into proper position for operation or cooperation with thefirst socket. This system, it will be seen, differs from other systemsin that there is always provided a path for the return movement of thetool during its operation to a point in proximity to the startingpoint,such return movement being the final course traversed by the tool towardthe starting-point and being the final course in which the bristles areinserted.

Obviously this system is applicable in either a socket-forming orbristle inserting orfilling machine, and I do not wish to be restrictedin the application of this portion of the invention to its use inconnection with any particular machine.

Having thus described my invention, what Iclaim as new, and desire tosecure by Letters Patent, is a 1.
